Be it known that we, CHARLES H. PnLToN and Geenen C. lrronnnrcn,citizens of the United States, residing at Springfield, in the county ofClark and State oi' Ghio, have invented certain new and usefulImprovements in Mowing Machines,- of which the following is aspecification.

@ur invention relates to mowing machines, it particularly relating toimprovements in the mechanism described in patent to Felton for mowingmachine, No. 943,266, dated Dec. 14C, 1909.

In the patent referred to there is described mechanism for adjusting thecutting devices ot' a mowing machine whereby the knife may be maintainedin proper alignment with its actuating mechanism and also in properregistry with the stationary cutter lingers, and the knife and thecutter bar maintained in proper relation with the line of draft, and inthat patent there is shown and described eccentric bearings for thecutter bar of an adjustable character for accomplishing the desiredresults, these eccentric bearings being clamped in split collars. Whenan adjustment is made, however, the relation between the walls of thesplit collars and the eccentric bearing blocks is necessarily changed asthe parts must occupy a more or less angular relation relatively to eachother which results in a less effective clamping area between thesurface of the split collars and the blocks.

The object of our invention is to improve the construction et thebearing blocks and the clamping members so that an effective and uniformclamping area will be maintained between the blocks and clamping membersin all positions of adjustments of the parts.

ln the accompanying drawings Fig. l is a top plan view of so much of amowing machine as is necessary to illustrate our improvements.

teierring to the drawings, l represents a yoke which forms a part ot atrame member (not shown) which supports the cutting devices. A shoe 2 ofusual form is pivotally connected with this yoke and has rigidlyconnected therewith a conventional linger bar 3 provided with the usuallinge 4 with which co-operatcs a knife 5 which is carried by the bar inthe usual way and has a connection through a pitman 6 with actuatingmechanism ot' the usual form whereby the knife may be reciprocated; theknife being provided with a ball 5" and the pitman with a socket G toreceive the ball to form the driving connection.

Formed on the shoe, preferably as an integral part thereof, are twoclamping members and associated with each ot' these clamping members isa companion clamping member 8 which is pivotally connected with theshoe. Each pair of clamping members is designed to receive and clamp ablock A9 which has an eccentric aperture l0 which receives a pin l1,which pins project loosely through apertures in the arms of the yoke l.Each block 9 has a hexagonal Hangs 9a to receive a wrench whereby itmay7 be turned for adjusting purposes. l

ln the present case the bearing block -9 is formed with a convexperiphery 9b and the clamping members 7 and 8 with concavebearingsurfaces 7a and 8a to receive the conver periphery ot the bearingblock; the surfaces 7a and 8a, when the parts are in clamping position,lying diametrically opposite each other. The clamping member 8 of eachpair ot clamps is secured to its companion clamp 7 by a bolt l2.

By such a construction it will be seen that when either one, or both, ofthe blocks rotate to change the angular relation of the parts foradjustment purpose, thereby changing the angular relation ot' the blocksand clamping members, the clamping surfaces of the clamping members willnevertheless impinge at all eltective points upon the clamping surfacesot the blocks and thereby maintain an eiective clamping area between theparts, thereby obviating any danger of slippage ot the hiocks in thechinipiiig members with consequent disarrangement ot the proper adjustedposition of the cutting` d vices.

Having thus described oiir invention, ive ciaimzl. In a machine ot thecharacter described, :i support, a inojer bar havinga knife cooperat'ngtherewith, and a pivoted ccnnection hetiveen said support and bar,including an eccentric biock and a chimp to holo. the biocir indii/tercer positions oit adjustment, said block and chimp havingcooperating roiindcd clamping;v faces so Yiforrgied as to permituniversal movement without diiiiinishingithe ei'ieet've ciainping` areaOt the faces, tor the purpose specified.

2. in a machine of the 'character described, a support, a linger harhaving a hnii'e cooperatinc` therewith, and a pivoted connect-ionbetween said support and bar, inciiiding an eccentric bloei; nd a clampto hold the saine iii different positions ot adjustment, one ot theparts included in said pivotal connection having` is, convex ciampiiigsurface and the other part a cooperatingconcave clampingl surface, torthe purpose speciiied;

3., In a machine of the character described, a support, a finger barhavinc` a kniie cooperating therewith, and a pivoted connection ietiveeii said support and ear including an eccentric block and a chimpto hold the block in diiiei'ent positions ot adjustment, said ciainpconsisting` ot a stationset or chi icing members, a pivot pin con-Ynecting each bloei; with said support, each of said biocirs and itscooperatingl clamping members having cooperating concave and convexclamping races, 'for the purpose speciiied.

5. in a machine ci? the character described, a yoke-shapedsupport,ating-ger bar having` a kniite cooperating therewith and a shoerigiif'iiy attached thereto, a pair ci' rigid clamping members on saidshoe, cach oi' said igid chinipiiitgmembers having a companion ciainpinomember pivoted to said shoe, :in eccentric block associated with eachset ot sa'd chiiiiping'ji` members, pivot pins eX- tending through thearms of said yokeshaped support, and eccentric apertures in said blocks,said blocks and their cooperatini;` cianiping` members havingcooperating` rounded chiinpiiin Jfaces.
